Motivation for jddd development

The jddd editor:

Components / widgets

Functionality

New jddd features:

The subversion browser

The plugin interface

Petra vacuum controls

Experience & Outlook



3

Motivation

We don't want do design all panels in the controls group (Flash: ~ 1300 control panels)

Non-programmers / subsystem experts should develop graphical control panels

Synaptical displays editor: simple creation of control panels with a set of standard components: text, buttons, graphical components…

Replace old ddd (DOOCS data display, C++)

→ jddd (Java DOOCS data display)



4

jddd

jddd implementation:

Use JAVA for platform independence

Standard JAVA technology (Swing, Java Beans)

Save panels in xml file format

We decided to write a completely new editor because:

Independence of external libraries

Highest flexibility

Demands on the editor:

Stability, extendability, ergonomic and intuitive machine interface

Import old ddd files

jddd new features

jddd new features:Subversion file browser

Plugin interface



12

jddd subversion browser

SubversionFile Browser:

• Central place for data storage

• Keep file history

• New developmentusing theSvnkit libraryhttp://svnkit.com



13

jddd plugin interface

Plugin Interface:

A plugin.jar is needed containing wrapper classes for all Java beans.

• ATKPlugin (Tango)• ACOPPlugin (Tine)



14

jddd new features

Jddd sample panels from

PETRA vacuum controls

LocationChooser: changes the base address of the whole panel

Pump Station Panel (imported from ddd)

Experience with jddd:

The jddd editor can be used for designing highly complex control panels.

The subversion browser keeps the control panels history and enables many users to work on the same panels.

The plugin interface allows other institutes to use jddd with their own Java beans.



20


Outlook on future jddd development:

API improvements:

Implementation of asynchronous DOOCS calls

Read history data from the data acquisition system (DAQ)

Improved interface to TANGO and new interface to EPICS control systems

New middle layer server for:

Caching the subversion file system

Keeping a list of file dependencies

Providing runtime statistics

Updating panels in running applications
